@ZZ whom, t may concern:

Be it known that I, MICHAEL JUNGEL, a citizen of the United States,residing' at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Veneer-Presses, of whichthe following is a full, clear, and exact speciiication.

My invention relates to that class of presses more generally used forpressing the veneers while the glue is hardening but it is also designedfor pressing or holding other material tity of such material at one timemay be readily introduced under the press and withdrawn therefrom.

A further object of my invention is to provide improved means wherebythe pressure at various points throughout the bed of the press may bevaried at will, so that in the event the material does not cover theentire bed the ends of the top plate will not be bent downwardly at theends of the material.

In order to accomplish the foregoing objects and certain other objectswhich will hereinafter appear, I employ certain features of noveltywhich comprise the invention and which will first be described withreference to the accompanying drawings and then more particularlypointed out in the claims. K

In the said drawings, Figure 1 is a side elevation of my improved press.Fig. 2 is a front view thereof, partly broken away. Fig. 3 is a viewsimilar to Fig. 1, showing the truck withdrawn. Fig. 4 is across-section of the bed on the line 4 4, Fig. 3. Fig. 5 is a detailside elevation of one of the springs and pressure-increasing bar,showing themanner in which it is used. Fig. 6 is an end view thereof.Fig. 7 is a detail perspective view of the pressure-increasing bar. Fig.8 is a side elevation of the lower part of the press 'and truck, showinga modiiication hereinafter described with the drawn; and Fig. 9 is a thetruck introduced.

The material to be introduced into the press is placed upon a truckcomprising a platform l and supporting-wheels 2, which, however, supportonly one end of the platform, while the other end of the platform issupported directly upon the bed 3 of the press and slides therealong,and the truck is pulled out or pushed in beneath the usual top plate 4.The material in the various figures ofthe drawings is represented by thedotted lines 5, and in Fig. 3 the truck is shown partially withdrawnwith the material supported thereon preparatory to being introduced,while in with the material introduced between the bed and the top platehe platform 1, however, serves as the direct support for the materialupon the bed 3 during the pressing operation, and in order that thewheels of the truck may be relieved of pressure at this time means areprovided whereby they will no longer be in contact with the iioor whenthe truck is in its inner position. In the exempliiication of theinvention shown in Figs. 1, 2, and 3 this is accomplished by mal ng orarranging the bed 3 on an incline with the highest platfor'rn 1, theplatform, the opposed faces of these two members are provided withmatched grooves 7, extending longitudinally of the boards of which theyare composed, as shown in Fig. 4.

The bed 3 is supported directly upon a plurality of cross I-bars 8, andthese take their support upon longitudinal I-beams 9, which are in turnsupported upon cross-sills 10, or any other suitable foundation for thebed may be employed.

with a ratchet-wheel 14 for turning the screw in the nut 15, fixed tooverhead cross-bars 16, and thereby raising and lowering the top plate4. The top plate is supported at its ends by two independentsupplemental screws 17 18, which have their lower ends IOO IIO

The bed 3 being on an incline and it being desirable that the pressurebe transmitted directly at right angles to the Jface of the bed, thestandards 27 are also inclined, as shown in Figs. 1 and 3, and that ofcourse determines a corresponding inclination in the other parts oi thesuperposed structure.

In the modification shown in Figs. 8 and 9 the bed 38L is level, and toprovide for the removal oi the wheels 2 lfrom the floor they are mountedupon eccentric journals 34, provided with a handle 35, which when turnedraises the wheels from the floor, and, if desired, this handle may be soset, as shown in Fig. 8, as to be pushed over the center automaticallyby a projection 36 when the truck is forced home. The inner end of thetruck, if desired, may be provided with an antifriction-roller 37 forsupporting it during its travel, and when in position for pressure theroller 37 passes down an incline 38 on the bed 3, and thereby allows theplatform 1 to settle irmly upon the bed.

I-Iaving thus described my invention, what I claim as new by LettersPatent, is-

1. A press for the purpose described comprising side standards, overheadcross-bars secured to the standards, a nut iiXed to the cross-bars, acentral main screw working in the nut, a support in which the lower endof the main screw is swiveled, longitudinal beams suspended from thesupport, a top plate, cross-beams secured upon the top plate, series ofleaf-springs secured in pairs to the cross-beams and suspended from thelongitudinal beams, cross-bars mounted upon the ends of the longitudinalbeams, supplemental screws. working in the cross-bars, and swivelconnections whereby the ends of the top plate' are suspended Jfrom thesupplemental screws.

` 2. A press for the purpose' described comprising a support,longitudinal beams suspended from the support, a top plate, crossbeamssecured upon the top plate, series of leaf-springs each having dependingend lips embracing the cross-beams, and suspended from the longitudinalbeams, and removable strips having enlargements at their ends andinserted between the springs and cross-beams and retained in position bythe depending provided with swiveled connection 19 oi any suitable formwith the top plate, while their upper ends pass loosely throughcross-bars 2O 21, respectively, supported upon two longitudinal I-beams22, the upper ends'of the screws 17 18 above the cross-bars 20 21 beingprovided with hand-wheels or nuts 23, threaded thereon and taking theirsupport directly upon the cross-bars 20 21, so as to j suspend the topplate 4 at its ends from these cross-bars. The longitudinal beams 22 aresecured to a central crossbar or support 24, having a boss 25, in whichthe lower end of the main screw 11 is rotatably secured or swiveled inthe usual way, so that when the screw 11 is rotated the cross-bar 24,together with the beams 22, the screws 17 18, and the top plate 4,suspended thereby, will be raised and lowered, the beams 22, andconsequently all parts connected therewith, being guided in thesemovements by guides 26, secured to the sides of the longitudinal beams22 and embracing the side standards 27 oi the press.

The downward pressure oi the main screw is communicated to the top plate4 through the intermediary of a plurality of leaf or semi-ellipticsprings 28 29, arranged in two series, one series under each of thebeams 22 and one pair of the springs 28 29 of each series beingsupported upon one of a series of cross I-beams 30, which are supporteddirectly upon the top plate 4, and thus impart the pressure of the mainscrew 11 uniformly to the work 5 upon the bed 3. In many instances,however, it is desirable to vary the pressure of the springs 28 29 atdifferent places in the length or the width of the top plate-as, forexample, where the work does not cover the entire bed-thus leaving theedges of the top plate where they project beyond the work unsupportedand liable to be bent'an objectionable extent or subjected to the samedegree of pressure as the part upon the work. In order to accomplishthis variation in the pressure, therefore, I employ a number ofremovable bars or strips 31, the detail of one of which is shown in Fi7, having enlargements 32 at their ends a apted to be inserted betweenthe springs and their respective beams 30 inserted or withdrawnaccordingly as it is desired to increase or decrease the pressure atthat point. In order j that the bars 31 may better remain in place, endlips. the ends oi the springs are formed or pro- MICHAEL JUNGEL. videdwith downwardly-proj cting lips or Witnesses:
